Introduction

not bad

Two Level Simplification

Example 3.1 Two-bit comparator

Good example

For EQ, xnor form uses 3 gates, but we cannot be sure about the # transistors because XNOR uses a lot of transistors

SNUON: 2 bit by 2 bit multiplier

Example 3.2

For Figure 3.21, if we count the \A as signal A with inverter, that will count as 2 additional transistors. But that is not the case. Most signals have their inverts provided as well, so we do not have to count the inverters.
